Applicationzfiled December 18, 1921; Serial No. 522,856;

My invention relates to improvements in fuel. saving devices and more particularly has reference to a device adapted for, attachmena upon the door: of; a furnace for heating the air preliminary to its combustion with the fuel in the furnace.-

In the accompanying drawings, I have illustratedlin Fig. l in side elevation, parts being broken away, a suitable form of device embodying an application of my invention as applied to a furnace'door. Fig. 2 is a view looking from right to left at Fig. 1. Fig. 3 is a longitudinal sectional view of the device shown in Fig. 1, and Fig. 4 is a view looking left to right at the device as shown in Fig. 1, and Fig. 5 is an enlarged detailed view parts being broken away illustrating the periphery of one of the discs or" partitions over and around which the air passes into the furnace.

6 indicates the furnace door upon the outer or left side of which is secured the inlet chamber 7 provided with central openings adapted to register with the openings 8 1n the shutter 9 which may be rotatably secured therein by any suitable means such as the button 10, thus controlling the amount of air entering the furnace through the device. The door being cut away as shown, the air passes therethrough into the first chamber 11 and through the neck 12 into the next chamber 13 where the air spreads radially in order to pass the disc 14, the periphery of which is preferably formed substantially as shown in Fig. 5. That is to say, the periphery is divided into segments, one of which is turned over in one direction as indicated at 15, the next remains substantially vertical, but is turned at each side forming blades such as 1617 and the next segment 18 is turned in a direction opposite to the segment 15, the distance between the outer ends of the segments and 18 being equal to the depth of the chamber 13, and so on the next and successive sets of segments are substantially likewise formed with the result that the air entering the furnace as aforesaid striking the disc 14 spreads radially to the peripheral margin thereof and.

encountering one set of segments such as 15 or 18 is bafiied and is obliged to pass through the space between the projecting segments at the side in the direction of which the air enters and in passing over the disc 14: some of the air striking one of the deflecting sides such as 16 or 17' is impelled from the radial to a. circular 1 or tangential direct on.

whirlingover the topor, perpihery ofthethe furnace door above the fuel may be suitably controlled by the damper and having entered the apparatus is drawn through by the draft or other suitable means in the course of which it is normally whirled and mixed insuring thorough contact with the walls of the apparatus, which being projected into the furnace above the fuel from the door thoroughly heats the air to considerable extent and the air upon leaving the apparatus is so spread as to come thoroughly into contact with the gases in the furnace and being at a sufficiently elevated temperature readily combine and enter into combustion therewith, the resultant products escaping in the usual manner.

The air entering beneath the grate ofthe furnace is burnt mostly lower down in the fire near the grate where the fuel is hottest and the unburnt products passing through the fuel being met by the heated air from the apparatus in the furnace door as afore said enters into combustion at that point, insuring a more perfect combustion before the final escape of the products thereof.

Of course it will be understood that various modifications may be made in the construction and arrangement of parts without departing from the spirit of the inven tion as claimed.

I claim 1. In an apparatus of the class described, circular partitions having segments at the periphery extending in opposite directions and segments intermediate of said first mentioned segments projecting at right angles to said partition and bent over at opposite sides.

2. In an apparatus of the class described, a series of intercommunicating chambers in axial alignment, said chambers of alternating sizes, discs across the larger chambers, air deflectors at the peripheries of said discs, and means admitting and discharging air through the axial center of said apparatus.

3. In an apparatus of the class described, a series of intercomrnunicating chambers in axial alignment, said chambers or alternating sizes. discs across the larger chambers, air deflectors at the peripheries of said discs, and means admitting and discharg ing air through the axial center of said ap-- paratus, said deflectors formed integrally with said discs.

4. In an apparatus of the class described, a chamber having an air inlet and an air outlet, and means within said chamber for whirling said air, said means comprising a disc With alternating and opposite offsets at the periphery and angular deflectors therebetween.

5. In an apparatus of the class described, an air inlet at the front thereof and an air outlet at the back thereof, and means around the axial center of said apparatus for whirling said air around said center as the same passes through said apparatus, said whirling means comprising deflectors around the inside of the rim of said apparatus and spaced apart lateral deflectors pointing alternately fore and aft of said apparatus between said first mentioned'de- In testimony whereof I hereunto aflix my
